The purpose of this study is to see if the investigators can obtain non-inferior clinical outcomes (similar numbers of oocytes) using the Cardinal protocol, a cost-conscious, low-intensity egg freezing protocol, compared to other routinely used high-intensity clinic protocols. This is a new program for Stanford's Fertility Clinic, so the investigators are assessing patient experience and cost-benefit of a low-cost, low-intensity approach that has demonstrated non-inferiority in IVF for infertility treatment, but has not been similarly evaluated in egg freezing. All enrolled participants will choose the Cardinal protocol or the routine high-intensity protocol designated by their physician. The investigators will then assess number of eggs retrieved, as well as patient satisfaction, cost, and time needed off work to complete the egg freezing cycle. The study's findings could ultimately open the door to implementation of lower-cost standardized protocols that would be more affordable and accessible to people who may otherwise not be able to pursue fertility preservation.
